34 THE NATIONAL PARK SERVICE 



surrounded by, but not included in, the area set apart by the 

 act of October i, 1890 (26 Stat. L., 650) for a national park 

 under the Secretary of the Interior. 



The act of April 28, 1904 (33 Stat. L., 478) directed the 

 Secretary of the Interior to ascertain what part of thg area 

 set aside by the act of 1890 was not necessary for park pur- 

 poses and could be returned to the public domain. In the fol- 

 lowing year, accordingly, certain lands were excluded from 

 the area originally set aside, and the remaining reservation 

 was named the Yosemite National Park (act of February 7, 

 1905; 33 Stat. L., 702). It was provided, however, that 

 revenues accruing from the lands excluded should go to the 

 park. With the formal acceptance by the United States 

 (Joint resolution of June 11, 1906; 34 Stat. L., 831) of the 

 recession by California of the lands given for a state park 

 in 1864 (California Session Law, March 3, 1905) the crea- 

 tion of the Yosemite as a national park was complete, the 

 lands receded being included in the national park created in 

 1890. 



Beginning with the season of 1891 troops were detailed to 

 guard the park, and this system continued except for short 

 intervals until 19 14, when they were withdrawn by agreement. 

 The act of June 6, 1900 (31 Stat. L., 618) directed the Sec- 

 retary of War to make troop details on request of the Secre- 

 tary of the Interior. As in the case of the Yellowstone, the 

 commander of the troops was acting superintendent. The 

 troops did not remain in the park during the winter, however, 

 and no permanent post was established. 



The act of December 19, 1913 (38 Stat. L., 242) granted 

 the city and county of San Francisco the right to create a 

 reservoir in the Hetch Hetchy Valley in the Yosemite Park 

 for the purpose of supplying the city with water. 



The act of June 2, 1920 (41 Stat. L., 731) accepted, on the 

 part of the United States, exclusive jurisdiction in the Yosem- 

 ite, Sequoia, and General Grant Parks.
